Let’s solve each percentage problem step by step.
Remember: To find a percentage of a number, you can convert the percent to a decimal and multiply.
For example:
- 10% = 0.10 → so 10% of 16 = 0.10 × 16 = 1.6
- 70% = 0.70 → so 70% of 38 = 0.70 × 38 = 26.6
We’ll go one by one.
---
1a. 10% of 0
→ 0.10 × 0 =
0
1b. 10% of 16
→ 0.10 × 16 =
1.6
---
2a. 70% of 38
→ 0.70 × 38
Break it down: 0.7 × 30 = 21, 0.7 × 8 = 5.6 → 21 + 5.6 =
26.6
2b. 50% of 36
→ Half of 36 =
18
---
3a. 80% of 28
→ 0.80 × 28
0.8 × 20 = 16, 0.8 × 8 = 6.4 → 16 + 6.4 =
22.4
3b. 70% of 48
→ 0.70 × 48
0.7 × 40 = 28, 0.7 × 8 = 5.6 → 28 + 5.6 =
33.6
---
4a. 30% of 6
→ 0.30 × 6 =
1.8
4b. 20% of 36
→ 0.20 × 36 =
7.2
---
5a. 20% of 22
→ 0.20 × 22 =
4.4
5b. 80% of 36
→ 0.80 × 36
0.8 × 30 = 24, 0.8 × 6 = 4.8 → 24 + 4.8 =
28.8
---
6a. 80% of 6
→ 0.80 × 6 =
4.8
6b. 20% of 44
→ 0.20 × 44 =
8.8
---
7a. 70% of 8
→ 0.70 × 8 =
5.6
7b. 60% of 22
→ 0.60 × 22
0.6 × 20 = 12, 0.6 × 2 = 1.2 → 12 + 1.2 =
13.2
---
8a. 90% of 12
→ 0.90 × 12 =
10.8
8b. 80% of 22
→ 0.80 × 22
0.8 × 20 = 16, 0.8 × 2 = 1.6 → 16 + 1.6 =
17.6
---
Final Answer:
1a. 0
1b. 1.6
2a. 26.6
2b. 18
3a. 22.4
